Fix failing tests in CachedBluetoothDeviceManagerTest

Remove unnecessary if statements that will cause the tests failing. This
checking will retrieve `mProfiles` in CachedBluetoothDevice which will
be empty in test cases. Without the if statement, things will still be
correct since there's another value checking if statement inside.
